MES quantified water loss and I&I for the town and delivered a final report with engineering estimates and a prioritized roadmap in 2024; follow-up work continues in 2026.

Town of Yampa wastewater plant and collection system
A 105,000 gpd replacement plant and targeted sewer lining, pipe replacement and manhole upgrades designed for the Town of Yampa.

About the project
The problem
The Town of Yampa's wastewater treatment plant had reached the end of its useful life. It could no longer meet the town's needs or its regulatory discharge requirements.
The town's wastewater collection system had also deteriorated. Rehabilitation was critical to keep service reliable and reduce ongoing maintenance.
The pathway
MES led the civil design for a new 105,000 gallon per day replacement plant. The team designed the site layout, grading, drainage and utility connections, and wrote the plans and technical specifications.
The civil work also covered the influent and effluent sewer lines, pre- and post-development drainage, floodplain work and Yampa River sections.
For the collection system, MES reviewed CCTV footage and inspection reports to find the problem areas. MES also built a sewer network priority table.
MES wrote the plans and technical specifications for the collection system improvements. The work lined existing pipelines, replaced some pipe by open cut and upgraded manholes.
MES also worked with town officials to prepare grant applications for the collection system improvements.
The result
The new plant is designed to meet effluent limits of BOD below 5 mg/L, TSS below 1 mg/L and TIN below 21 mg/L.
The CCTV review let MES aim the rehabilitation at the most critical areas of the system.
Collection system construction was under way by July 2024. New sewer pipe was going into open trench, and new precast manholes were going in.
